Allergic Rhinitis in Children

What is allergic rhinitis in children?

Rhinitis is a reaction that happens in the eyes, nose, and throat. It occurs when allergens in the air trigger the release of histamine and other chemicals in the body. Normally allergens are harmless. But when a person has allergies, the body thinks these allergens are harmful and attacks them. Special cells called mast cells release chemicals including histamine. The chemicals irritate nearby nasal tissue. This causes nasal allergy symptoms. When this happens in the lungs' breathing tubes, it can cause asthma symptoms such as coughing and wheezing.

Allergic rhinitis can happen on a seasonal basis or year-round. There is often a family history of allergic rhinitis, eczema, asthma, or food allergy.

What causes allergic rhinitis in a child?

The most common causes of allergic rhinitis in children are:

Pollen from trees, grass, or weeds

Dust mites

Mold

Cockroach waste

Animal dander

Things such as strong odors and tobacco smoke can cause similar symptoms to allergic rhinitis. But these substances are irritants not allergens.

Which children are at risk for allergic rhinitis?

Children with other allergic diseases (such as eczema, food allergy, and asthma) are more likely to also have allergic rhinitis. About 8 out of 10 children with asthma also have allergic rhinitis. For these children, allergens are a common cause of asthma attacks. Children whose parents have allergies are also at greater risk of developing allergies.

Controlling allergies may help control asthma and eczema in some children.

What are the symptoms of allergic rhinitis in a child?

Each child may experience symptoms differently. Common symptoms include:

Sneezing

Stuffy nose

Runny nose

Itchy nose, throat, eyes, and ears

Nosebleeds

Clear drainage from the nose

Children with year-round allergic rhinitis may also have these symptoms:

Ear infections that keep coming back

Snoring

Breathing through the mouth

Not doing well in school

A line or crease across the bridge of the nose from often wiping or scratching the itchy nose

The symptoms of allergic rhinitis may look like other conditions or health problems. Always talk with your child’s healthcare provider for a diagnosis.

How is allergic rhinitis diagnosed in a child?

In most cases, your child’s healthcare provider makes the diagnosis based on a full health history and physical exam. During the exam, your child’s provider may also find:

Dark circles under the eyes

Creases under the eyes

Swollen tissue inside the nose

If this is the case, then the provider may refer your child to see an allergist. An allergist is a healthcare provider who is trained to do allergy skin testing. This testing will tell you exactly what things are causing your child to have symptoms.

How is allergic rhinitis treated in a child?

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.

Treatment choices may include:

Antihistamines

Nose sprays

Decongestants

Medicines for asthma symptoms

Allergy shots

What can I do to prevent allergic rhinitis in my child?

Experts don't know how to prevent a person from developing allergic rhinitis. But you can help prevent the symptoms by:

Controlling your child's environment, such as using air conditioning during pollen season

Having your child stay away from areas where there is heavy dust, mites, molds

Keeping your child away from pets

When should I call my child’s healthcare provider?

Call your child’s healthcare provider if your child has:

Symptoms that get worse

New symptoms
